I’m using System.console().readPassword() to read input from the console without echoing characters. This works find on OpenJ9 on my Mac terminal and when using QSHELL in a 5250 terminal. However when running via SSH to the IBMi it fails:

Exception in thread "main" java.io.IOError: java.io.IOException: Qyj9SetEcho failed

Is this a known limitation or a bug? Google search came up with nil.
